ADV7344 Datasheet, Funktion
Data Sheet
GENERAL DESCRIPTION
The ADV7344 is a high speed, digital-to-analog video encoder
in a 64-pin LQFP package. Six high speed, NSV, 3.3 V, 14-bit
video DACs provide support for composite (CVBS), S-Video
(YC), and component (YPrPb/RGB) analog outputs in standard
definition (SD), enhanced definition (ED), or high definition
(HD) video formats.
The ADV7344 has a 30-bit pixel input port that can be configured
in a variety of ways. SD video formats are supported over an
SDR interface and ED/HD video formats are supported over
SDR and DDR interfaces. Pixel data can be supplied in either
the YCrCb or RGB color space.
The ADV7344 also supports embedded EAV/SAV timing codes,
external video synchronization signals, and I2C® communication
protocol.
In addition, simultaneous SD and ED/HD input and output is
supported. Full-drive DACs ensure that external output buffering
is not required, while 216 MHz (SD and ED) and 297 MHz
(HD) oversampling ensures that external output filtering is not
required.
Cable detection and DAC autopower-down features keep power
consumption to a minimum.
Table 1 lists the video standards directly supported by the
ADV7344.
